What's the difference between snowball and avalanche?

Snowball pays off the smallest balance first regardless of interest rate, building momentum through quick psychological wins. Avalanche pays off the highest interest rate first, which minimizes total interest paid mathematically. Avalanche is always at least as cheap as snowball for the same debts — the question is really which approach you'll actually stick with.

How does the extra payment get applied?

Every debt gets its minimum payment each month. Any extra amount you specify, plus the minimum payments freed up from debts you've already paid off, goes entirely toward the current priority debt based on your chosen strategy — accelerating that one debt while others stay at their minimum.

Is one strategy always cheaper?

Avalanche never costs more in total interest than snowball for the same debts and extra payment amount — but the difference can be small if balances and rates are fairly similar across your debts, in which case picking whichever keeps you motivated to keep paying is a completely reasonable choice.
